Combined type super-high-rise structure and construction method

Abstract

The invention relates to a combined type super-high-rise structure and a construction method. The combined type super-high-rise structure comprises a reinforced concrete frame-core tube structure located at the bottom of the combined type super-high-rise structure, and a rigid column steel beam frame-core tube structure fixed to the top of the reinforced concrete frame-core tube structure, a reinforced concrete frame and a core tube in the reinforced concrete frame-core tube structure are constructed by adopting an overall lifting scaffold, a core tube in the rigid column steel beam frame-coretube structure is constructed by adopting an overall steel platform formwork system, and a rigid column steel beam frame is constructed by adopting the overall lifting scaffold. The overall lifting scaffold system is adopted in the reinforced concrete frame area, the core tube and the reinforced concrete frame are constructed simultaneously, the altitude difference working face is reduced, and the construction speed is increased. In the rigid column steel beam frame area, the internal core tube structure is firstly constructed by adopting an overall climbing steel platform system, steel beamson the periphery is convenient to connecte to the core tube, then the rigid column steel beam frame is constructed by adopting the overall scaffold, and fast construction is achieved.

Description

technical field [0001] The invention relates to the technical field of super high-rise structures, in particular to a combined super high-rise structure and a construction method. Background technique [0002] In the conventional super high-rise building structure system, there are generally two layout schemes: reinforced concrete frame-core tube structure and stiff concrete column steel beam-core tube structure. However, the working height of the former is generally 200-250m at most. When this height range is exceeded, the self-weight of the structure will increase sharply, resulting in a sharp increase in seismic response, which puts high requirements on the seismic performance of the structure; for the latter, although it The applicable height is relatively high, and it can be used at a height of 300m or more, but there is also the problem of a large amount of steel structure, and the economy is poor. In addition, there is also the problem that the net height of the struc...

However, the working height of the former is generally 200-250m at most. When this height range is exceeded, the self-weight of the structure will increase sharply, resulting in a sharp increase in seismic response, which puts high requirements on the seismic performance of the structure; for the latter, although it The applicable height is relatively high, and it can be used at a height of 300m or more, but there is also the problem of a large amount of steel structure, and the economy is poor. In addition, there is also the problem that the net height of the structure is much smaller than the former.
